Mike has an attic full of loose-fill insulation and needs to renew his ceiling. But he doesn't dare take the old drywall down because of all that insulation. So how do you put new drywall over the old?

We caught a consumer in the hardware store and he was asking about the leaking roof on his new addition in the Beaches area of Toronto. Often in that area, a back porch is converted into living space with what we call a "compact roof" -- a roof/ceiling assembly that is about one foot thick with i...
CUTTING FIBERGLASS STRAIGHT AND SQUARE
It is always easier to cut fiberglass batt insulation if you compress it down as flat as possible. That way you can get through in one pass. Using a piece of plywood gives you a straight edge at the same time.
There is a special devic...

Aluminum reflectors will turn back RADIATION heat losses into the house, and in fact help to limit heat losses. However, they will only work if there is at least a half-inch air space in front of the reflective surface and the surface remains clean an...

It comes in two basic varieties, solvent based and water based, the later often being called "green" or "solvent free". Although thes...

Walls often have air spaces hidden somewhere between the siding on the outside and the drywall on the inside. Some are accidental -- some on purpose, even code required -- some served a purpose at one time in history but because of the evolution of construction, are no longer useful -- some a...
Fiberglass batts, mineral wool batts and all kinds of rigid foam boards are commonly used to insulate basements both inside and outside.
One of the critical rules when insulating basements on the inside is that there must be no air space between the insulation and the wall. (see no air space beh...
